Why is everyone whining. Get over it we made a deal lucky got better its a game that you all seem to take a little to serious.
Because for GMs who put a lot of time into the game, its frustrating to see the entire game shift because someone else makes a poor strategic decision.
Its a dynamic that happens in a lot of other games, if you play a crunchy strategy game that's a 3+ hour commitment only to see someone check out an hour in and then make poor moves while texting on their smartphone resulting in your competitor getting a huge leg up its massively frustrating.
It's also a part of the games typically. Frankly finding lopsided trades is the entire point of the CB draft, which is why I wouldn't enjoy playing.
I like discussing basketball, I don't like sending 30 PMs a day cold calling people and then being a snake-oil salesmen when I know they're going to get killed if I successfully talk them into the deal.
